Drones Taking the Lava's Pulse

For the reconstruction of the LP-2 road in La Palma (Canary Islands), we are deploying drones equipped with infrared thermography to monitor the thermal evolution of the lava, ensuring both the safety and feasibility of the operations.

The 2021 eruption of the Tajogaite volcano in La Palma (Canary Islands) buried the LP-2 road while it was undergoing construction. We are currently rebuilding the section between kilometers 40 and 43, contending with the high temperatures that still persist within the lava field.

“Constructing this new road across the lava field necessitates a thorough assessment of the ground's thermal conditions, as volcanic lava flows can retain high temperatures for many years,” explains Juan Antonio Romero, Head of Topography at Sacyr Engineering in La Palma.

We have addressed this challenge by deploying drones equipped with infrared thermographic cameras for the capture, analysis, and thermal modeling of the affected terrain.

 

 
 

This technology enables us to identify areas with significant thermal activity, evaluate the technical feasibility of the proposed route, and provide recommendations to ensure safe operations for our professionals and partners.

Furthermore, this detailed analysis helps anticipate potential impacts on the road pavement structure and bituminous mixtures, as thermal variations can alter their cohesion, stiffness, and durability. This, in turn, informs the design and construction decisions for the future pavement.

This project is spearheaded by the Canary Islands Ministry of Public Works, which awarded the contract to the JV TAJUYA joint venture (comprising Sacyr Engineering and Infrastructure, Traysesa, Herquipalma, and Los Volcanes). The project is slated for completion in 2028.
 

 

 
 

Thermal Radiation Measurement

 

Infrared thermography is a remote sensing technique that detects thermal radiation emitted by objects based on their surface temperature. In the geotechnical field, this tool has proven to be an effective method for:


•    Identifying areas of residual volcanic activity.
•    Detecting active fractures and gas emissions.
•    Analyzing cooling processes in lava flows.
•    Evaluating the thermal stability of ground for civil engineering projects.


“Through the acquisition and processing of infrared images, we have generated georeferenced heat maps and graphs that illustrate the thermal evolution. The DJI MATRICE 350 RTK drone, equipped with a camera, can detect temperatures ranging from 0 to 550 degrees Celsius,” explains Juan Antonio Romero.

“This undertaking combines advanced technologies in remote sensing, thermal photogrammetry, and geospatial analysis. As a result, we enhance the road's quality and, crucially, improve site safety and occupational health,” he concludes.

Capturamos CO₂ industrial para hacer más sostenible nuestra agua desalada

En la desaladora de Sohar (Omán) hemos conectado industria y gestión del agua, ya que utilizamos las emisiones de chimeneas industriales para remineralizar agua desalada. 

Hemos puesto en marcha una iniciativa pionera en la desaladora de Sohar (Omán) para conectar industria y gestión del agua: capturamos CO₂ procedente de chimeneas industriales para utilizarlo en la remineralización del agua desalada. 

El proyecto demuestra cómo la innovación y la colaboración entre sectores pueden reducir emisiones, optimizar costes y acelerar la sostenibilidad.

Aunque la producción de acero y la desalación de agua parecen actividades ajenas, el hub industrial de Sohar ha demostrado que pueden ser complementarias. 
 
La planta Sohar 4 IWP, gestionada por Sacyr Agua, necesita CO₂ para estabilizar el pH del agua producida, evitar incrustaciones en las redes de distribución y garantizar un agua segura y apta para usos humanos, agrícolas e industriales.

 

 
 

Tradicionalmente, este CO₂ se adquiría a proveedores externos, con un elevado coste económico y energético. La proximidad de grandes emisores industriales dentro del propio hub abrió la puerta a una solución más eficiente: capturar el CO₂ en origen y reutilizarlo localmente.
 
Simbiosis industrial con impacto ambiental y económico
 
La iniciativa, impulsada por Abdullah Al Sadi, director del servicio de operaciones de la planta de Sohar, permite transformar una emisión industrial en un recurso clave para el tratamiento del agua. Este modelo de simbiosis industrial reduce emisiones en origen, mejora la calidad del agua producida y optimiza los costes operativos.
 
“El uso de CO₂ capturado nos permite mejorar la calidad del agua mientras reducimos emisiones directamente en su origen”, explica Al Sadi.
 
El proyecto fue reconocido con el Premio Innovadores Naturales 2025 de Sacyr, en la categoría Somos Excelencia.

Eficiencia operativa 
 
La planta Sohar 4 IWP produce cerca de 250.000 m³ de agua al día. Actualmente utiliza unas siete toneladas diarias de CO₂, aunque se espera que alcance las 12 toneladas en los próximos años.

La captura local del CO₂ elimina prácticamente los costes logísticos y permite reducir el coste del gas en torno al 40 %.

 

 

 
Menos huella de carbono y menos productos químicos
 
Aunque el proceso no reduce la energía necesaria para desalar, sí disminuye la huella de carbono del agua producida, al sustituir CO₂ de origen fósil comprado externamente por CO₂ capturado de la industria local.

Además, el uso de CO₂ capturado reduce la necesidad de otros productos químicos como la cal hidratada, el carbonato o el bicarbonato sódico, y permite optimizar el uso de cloro. Todo ello se traduce en menor impacto ambiental, menores costes operativos y una química del agua más eficiente.

Este enfoque también favorece el acceso a ventajas regulatorias, una mayor aceptación social y una mejor posición competitiva en mercados cada vez más exigentes en sostenibilidad.
 
Mirando al futuro
 
Tras dos años de desarrollo, el proyecto entra ahora en una nueva etapa centrada en consolidar pilotos, obtener permisos y escalar hacia soluciones comerciales replicables en otros entornos industriales.

Un nuevo ejemplo de cómo la innovación y la colaboración intersectorial pueden convertir los grandes retos ambientales en oportunidades compartidas.

Sacyr-backed OSP consortium begins construction on new Ontario Science Centre P3 project in Canada

  • The project, encompassing design, construction, financing, and maintenance, is valued at C$1.04 billion (€645 million).

The Sacyr-backed Ontario Science Partners (OSP) consortium has commenced construction on the new Ontario Science Centre in Canada. Ontario Premier Doug Ford presided over the groundbreaking ceremony held in Toronto.

The contract for the new Ontario Science Centre encompasses the design, construction, financing, and 30-year maintenance (DBFM), as well as the rehabilitation of the iconic Cinesphere and Pods at Ontario Place. The contract is valued at C$1.04 billion (€645 million).

The OSP consortium is comprised of John Laing Limited, Sacyr Infrastructure Canada Inc, and Amico Major Projects Inc.

A joint venture formed by Sacyr and Amico is tasked with executing the design and construction of the project, which will generate significant activity in the area and long-term employment.

The new Ontario Science Centre is a key project for the Government of Ontario to revitalize Ontario Place, a lakeside entertainment area that will be transformed into a modern cultural hub and one of Canada's primary destination attractions.

The project covers a total area of approximately 34,900 sqm, of which 28,300 sqm correspond to the construction of the new facility and approximately 6,600 sqm to the renovation of the Pods and the Cinesphere.

The Ontario Science Centre will incorporate sustainability objectives, such as LEED Silver certification, optimized energy performance, and the reduction of greenhouse gas emissions.

The design is led by the renowned Canadian firm Hariri Pontarini Architects, in association with the prestigious international studio Snøhetta.

Sacyr's first P3 project in Canada

This project, fulfills one of the objectives of the 2024-2027 Strategic Plan: to increase its concession portfolio in English-speaking countries.
